Anyone installing this on their local machine is a little crazy :). I have it running in Docker on a small VPS, all locked down.
However, it does not address prompt injection.
I can see how tools like Dropbox, restricted GitHub access, etc., could all be used to back up data in case something goes wrong.
It's Gmail and Calendar that get me - the ONLY thing I can think of is creating a second @gmail.com that all your primary email goes to, and then sharing that Gmail with your OpenClaw. If all your email is that account and not your main one, then when it responds, it will come from a random @gmail. It's also a pain to find a way to move ALL old emails over to that Gmail for all the old stuff.
I think we need an OpenClaw security tips-and-tricks site where all this advice is collected in one place to help people protect themselves. Also would be good to get examples of real use cases that people are using it for.
1. Use Gmail's delegate access feature instead of full OAuth. You can give OpenClaw read-only or limited access to a primary account from a separate service account.
2. Set up email filters to auto-label sensitive emails (banking, crypto, etc.) and configure OpenClaw to skip those labels. It's not perfect but adds a layer.
3. Use Google's app-specific passwords with scope limitations rather than full OAuth tokens.
For the separate Gmail approach you mentioned, Google Takeout can help migrate old emails, but you're right that it's a pain.
Totally agree on needing a security playbook. I actually found howtoopenclawfordummies.com has a decent beginner's guide that covers some of these setup patterns, though it could use more advanced security content.
The real challenge is that prompt injection is fundamentally unsolved. The best we can do right now is defense-in-depth: limited permissions, isolated environments, careful tool selection, and regular audits of what the agent is actually doing.
